  • a resilient, rubber-like cable grommet 88 is fitted over the two runs of the cable and has a portion 90 (FIG. 1) thereof that telescopes within the base section 32.
  • the portion 90 has a recess 92 which receives a companion-shaped inwardly projecting bead on the base section 32.
  • the grommet 88 may be split in order that it may be inserted onto the two runs of the cable. However, after installing the grommet, any openings between the cable and the grommet may be sealed with a suitable tape.
  • a suitable potting compound 94 may be introduced into the passageway 36 through the upper end thereof.
  • the passageway 36 is, in effect, a chamber that is closed off at its lower end by the grommet 88.
  • the potting compound may, forexample, be a curable polyurethane resin.
  • the potting compound 94 substantially encapsulates the cable runs in the region of the inner and outer sheath clamps, leaving the exposed splicing loop 38 for closure by the cover 8.
  • the bracket 80 may be a generally C-shaped member having one or more dielectric terminal boards 96 secured thereto, as seen in FIG. 1.
  • the end of the bracket 80 that is remote from the base 4 has an outwardly opening U-shaped portion 98 that is covered with an insulating material and which receives and supports the core wires of the cable loop 38. Consequently, when the cover 6 is removed, the cable loop 38 and terminal boards 96 remain in place and are accessible for connecting or disconnecting the service wire pairs 44.
  • a selected pair of core wires from the loop 38 are connected to a pair of terminals on one of the terminal boards 96.

  • the service wires may be directly spliced to the cable core wires, bypassing the terminal boards, if desired.
  • Each service wire pair 44 contains the individually insulated wires with a metallic grounding shield 100 (FIG. 1) surrounding the wire pair and a plastic insulating sheath 101 surrounding the metallic shield 100.
  • This outer insulating sheath 101 may be stripped away over a short length in order to expose the shield 100 so that the service'wire pair may be grounded through the mounting bracket 80.
  • the mounting bracket has a grounding block 102 (FIGS. 1 and 12) secured thereto as by screw 104. Screw 104 is also threaded into a movable block 106 which cooperates with the block 102 to form a generally rectangular opening 103 at which the grounding shield 100 is clamped.
  • Additional service wire grounding assemblies like that shown in FIG. 12 may be provided for in any suitable manner on the bracket 80 for each pair of service wires. This may be done by mounting a cross strap 107 (shown in FIG. 11) which may be arcuate in configuration when viewed along the longitudinal center line of the base 4.
  • tubular circumferentially disposed projections 108 integrally formed on the base are tubular circumferentially disposed projections 108, there being six such projections shown in the present form of the invention.
  • Each projection provides a port for receiving a pair of service wires 44; however, these tubular projections may be closed off and sealed when not in use.

  • the bore of the tubular projection 108 includes a conical portion 116 so that upon tightening of the nut 114, the spacer 112 applies pressure to the bushing 110 forcing the latter against the conical surface 116. This causes the bushing to grip the outer sheath of the service wire pair and form a seal. If a tubular projection 108 is not is use, it may be sealed off by an imperforate bushing and an imperforate disc. Normally potting compound is not introduced into the projections 108 in the region adjacent to the bushing 110 although this may be done if desired.
